Jenkins declarative pipeline conditional post action - jenkins

Question

I am using Jenkins declarative pipeline and want to perform some post build actions depending on the build status.
To be more precise, I want to send an email when the build status changed (from success to failure, or success to unstable, or failure to success).
Here is my pipeline:
pipeline {
agent none
stages {
stage('test') {
agent any
steps {
sh './tests.sh'
}
}
}
post {
changed {
// Send different emails depending on build status
// Success -> anything else
// Anything else -> Success
}
}
}
Any idea ?

Answer 1

For writing conditions you can define your own methods.
For example, if you want to send an email only when the build status changes:
def notifyStatusChangeViaEmail(buildStatus) {
def status
switch (buildStatus) {
case 'SUCCESS':
status = 'is now green again!'
break
case 'UNSTABLE':
status = 'has become unstable..'
break
case 'FAILURE':
status = 'has turned RED :('
break
}
emailext (
subject: "Job '${env.JOB_NAME}' ${status}",
body: "See ${env.BUILD_URL} for more details",
recipientProviders: [
[$class: 'DevelopersRecipientProvider'],
[$class: 'RequesterRecipientProvider']
]
)
}
pipeline {
...
post {
changed {
// Will trigger only when job status changes: GREEN -> RED, RED -> GREEN, etc
notifyStatusChangeViaEmail(currentBuild.currentResult)
}
}
}
Ideally, you would also want to put notifyStatusChangeViaEmail method definiton in your shared pipeline library so that it could be re-used in other jobs/pipelines.

Refer to this pipeline:
post {
success {
emailext (
subject: '${DEFAULT_SUBJECT}'+'SUCESSFUL',
body: '${DEFAULT_CONTENT}',
to: '${EMAIL_RECIPIENTS}'
);
slackSend (color: 'good', message: ":csp_operational: ${env.JOB_NAME} - #${env.BUILD_NUMBER} Success (<${env.BUILD_URL}|Open>)");
}
failure {
emailext (
subject: '${DEFAULT_SUBJECT}'+'FAILED!',
body: '${DEFAULT_CONTENT}',
to: '${EMAIL_RECIPIENTS}'
);
slackSend (color: 'danger', message: ":x: ${env.JOB_NAME} - #${env.BUILD_NUMBER} Failure (<${env.BUILD_URL}|Open>)");
}
}
You can set the Default Email parameters using Extended Email Plugin, Jenkins-> Configure Jenkins -> Extended Email Configuration.

Exemple : failure & unstable to success
if (currentBuild.result == 'SUCCESS') { if(hudson.model.Result.FAILURE.equals(currentBuild.rawBuild.getPreviousBuild()?.getResult()) || hudson.model.Result.UNSTABLE.equals(currentBuild.rawBuild.getPreviousBuild()?.getResult())) {
SEND MAIL()
}
}

#psalvi was imho on the right track, but #mikael-gibert wanted in his comment to get notifications only for the first fixed build. Jenkins declarative pipelines can do that, see https://www.jenkins.io/doc/book/pipeline/syntax/#post. Here an example:
pipeline {
// [...]
post {
always {
script {
// Examples of stuff you could do, based on some custom parameters and functions
if (params.buildAndPublish && branchIsMain()) {
currentBuild.description = 'NOT promoted '
}
currentBuild.description = (currentBuild.description ?: '') + '[' + (params.customArtifactVersion ?: mavenArtifactVersion) + ']'
if (params.buildAndPublish) {
// Tell Bitbucket about this build and its result
notifyBitbucket(credentialsId: config.credentialsId)
// Archive test results
junit(allowEmptyResults: true, testResults: "**/target/surefire-reports/**.xml,**/target/failsafe-reports/**.xml")
}
}
}
failure {
emailext recipientProviders: [culprits(), requestor()],
subject: "[Jenkins] Build failed: ${env.JOB_NAME} #${env.BUILD_NUMBER}",
body: "Hello,\n\nBuild failed: ${env.JOB_NAME} / ${env.BRANCH_NAME} #${env.BUILD_NUMBER}.\nDetails: ${env.BUILD_URL}\n\nJenkins"
}
fixed {
emailext recipientProviders: [culprits(), requestor()],
subject: "[Jenkins] Build fixed: ${env.JOB_NAME} #${env.BUILD_NUMBER}",
body: "Hello,\n\nBuild fixed: ${env.JOB_NAME} / ${env.BRANCH_NAME} #${env.BUILD_NUMBER}.\nDetails: ${env.BUILD_URL}\n\nJenkins"
}
}
}
